Answer:
Option 3 -
Step-by-step explanation:
Given : Options in the figure.
To find : Which of the following is a complex number?
Solution :
Complex number is defined as the number which contains real number along with imaginary number.
The complex number is in the form of a+ib.
Now, we determine one by one.
Option 1 - -7
-7 is the real number not complex.
Option 2 -
is the real number not complex.
Option 3 -
is in the form a+ib so it is a complex number.
Option 4 -
is the real number not complex.
Therefore, Only option 3 is the complex number.
B. The point shared by a triangle's altitudes.
C. The centroid.
D. The orthocenter.
The graph of f(x) = 3x is reflected across the x-axis is g(x) = f(-x) = 3x.
A graph can be defined as a pictorial representation or a diagram that represents data or values.
Reflection across the x-axis is defined as reflecting a point across the x-coordinate and y-coordinate change places, and When we have a point (x, y) and we reflect it over the x-axis, the result of the reflection is the point (x, -y)
To determine the graph of f(x) = 3x is reflected across the x-axis.
So the graph of f(x) = 3x is reflected across the x-axis.
⇒ g(x) = f(-x) = 3x
Hence, the graph of f(x) = 3x is reflected across the x-axis is g(x) = f(-x) = 3x.

Answer:
g(x) = -f(x)
Step-by-step explanation:
When we have a point (x, y) and we reflect it over the x-axis, the result of the reflection is the point (x, -y)
